POLE OR CURTAIN RING.

SPECIFICATION forming part of Letters Patent No. 418,992, dated January7, 1890.

Application filed December 6 1888. Serial No. 292,850. (No model.)

T0 all whom t may concern:

Be it known that I, HORACE E. SWIFT, a citizen of the United States, anda resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented new and useful Improvements in Pole orCurtain Rings, of which the following, taken in connection with theaccompanying drawings, is a specification.

This invention relates to improvements in pole or curtain rings, and itis carried out as follows, reference being had to the accompanyingdrawings, wherein- Figure l represents an end elevation of the improvedring, and Fig. 2 represents a side elevation of it, showing it assuspended on a pole or curtain-rod and lshowing its expansive endslocked together ready for use. Fig. 3 represents a longitudinal sectionof the improved ring, showing it as attached to the upper edge of acurtain. Fig. l represents a plan view of the ring, shown as laid outstraight before being curved, and Fig. 5 represents a cross-section onthe line X X shown in Fig. 4.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

This invention has for its object to provide a novel curtain-pole ring,whereby the curt-ain can be suspended without perforating it by pins;and to such end the invention consists in the features of constructionhereinafter described and claimed.

In the drawings I have represented the rings as composed of a core ofspring-metal Wire a a, inclosed by a metal cover b, also preferably madeof spring metal. The Wire a c extends beyond the ends of the cover l),and has in one end a loop or slotted eye or perforation a', as shown,and in its other end a pair of hooks a a, adapted to be locked to theloop or slotted perforation a when the device is to be used, as shown inFigs. l and 2. The ring when nished is to be given the proper anddesired expansive spring force, so as to automatically hold theexpansive ends of it locked together, as shown in Figs. l and 2, thusleaving it always ready for use.

Then it is desired to attach the curtain or cloth c to the ring, allthat is necessary to do is to grasp the ring and compress itsufficiently to disengage the hooks a a from the eye a', after which theupper edge of the curtain is introduced between said parts, and byletting go the hold of the ring it will automatically expand and causethe curtain to be pinched and held by the hooks or prongs a a and theeye or clasp a', as shown in Fig.

CZ represents a curtain pole or rod, on which the rings are located, asusual.

For the purpose of producing the pole-ring economically andconveniently, the core is composed of a single piece of wire doubledupon itself, with the main limbs or members a a running parallel and theends of the wire bent laterally apart and formed into the two separatedand curved or segmental-shaped hooks a a, while the loop a is formedwhere the wire is bent to double it `upon itself. The hooks a ride overthe upper part of the loop c. and curve into the latter, so that thecurtain will be pressed into the loop, and thus be held or grippedwithout perforating it, which is an advantage.

IVhat I wish to secure by Letters Patent and claim is- 1. An expansiblecurtain-pole ring comprising the parallel wires a a, formed at oneextremity into a loop a and at the other extremity spread laterallyapart and bent into two separated and curved hooks a a, which ride overthe upper side of the loop and curve into the latter to press thecurtain into said loop, and thus hold without perforating the curtain,substantially as described.

2. An expansible curtainpole ring comprising a wire doubled upon itselfto form two parallel members a a, having at one extremity the loop a andthe other extremity the two separated curved hooks a, which ride overthe upper side of the loop to press the curtain thereinto, substantiallyas described.

3. An expansible curtain-pole ring consisting of a wire core having atone extremity a loop o/ and at the other extremity two separated curvedhooks a, and the metal eastwo subscribing Witnesses,A on I@his 1st dayof ing Y), composed of L single strip of metal November, A. D. 1888.folded around and inelosing the Core between i 1 the loop and the twohooks, substantially as HORACE E' SVIFT 5 described. Vitnesses: I

In testimony wher-eof I have signed my ALBAN ANDREN, name to thisspecification, in the presence of SELMA R. SCHELIN.
